Polymer dispersal in solution

In addition to the level of filtration that is performed in preparing polymer solutions, care must be taken in the amount and intensity of mixing that is applied in making up the original solution in order to avoid uncontrolled mechanical degradation of the polymer molecules in solution. In this respect, synthetic polymers are much more sensitive than xanthan and other 

Note also that a number of additives may be put into a polymer solution, e.g. biocide, stabilisers, salts. Precisely how these should be added may be important (e.g. Wellington, 1980), and the manufacturer s recommendations should be followed where appropriate. Table 3.3 summarises the author s views on the levels of preshearing and filtration required in the preparation of polymer solutions for various types of laboratory test. However, the tests and measurements themselves are discussed in the appropriate later chapters.
